Room cooling/heating hot water supplying apparatus

PURPOSE: To effectively and smoothly recover refrigerant from a heat exchanger which is not used by effectively switching a refrigerant circuit in a hot water supply, room heating/cooling and room cooling time concurrent hot water supplying apparatus. CONSTITUTION: A four-way valve 22 is connected to a discharge refrigerant tube of a compressor 21, a four-way valve 23 is connected to a first outlet of the valve 22, and a second outlet of the valve 22 is connected to an input of a hot water supply heat exchanger 24. An outlet side of the exchanger 24 is divided into two directions through a check valve 32, one side of which is coupled to a cold/warm water heat exchanger 25 through a two-way valve 28 in parallel with a check valve 30 and an expansion mechanism 26, and the other end of the exchanger 25 is coupled to the valve 23. The other side divided in the two directions through the valve 32 is connected to an air heat exchanger 33 through a two-way valve 29 in parallel with a check valve 32 and an expansion mechanism 27, and the other end of the exchanger 33 is coupled to the valve 23. The valves 22, 23 are connected in series through a tube 35, and connected to a gas/liquid separator 34, which is coupled to the compressor 21. COPYRIGHT: (C)1993,JPO&Japio
